CMIT/MIT (Chloromethylisothiazolinone/Methylisothiazolinone) is a broad-spectrum, non-oxidizing biocide. It works by inhibiting the growth of bacteria, fungi, and algae by disrupting their cell metabolism.
Key Characteristics:
- Broad Spectrum: Effective against both Gram-positive and Gram-negative bacteria.
- Low Dosage: Extremely powerful at low concentrations (ppm levels), reducing your overall raw material costs.
- Eco-Friendly: Rapidly degrades into non-toxic components, making it ideal for environmental compliance.
What is Isothiazolinone (CMIT/MIT) Used for
- Paints and Coatings: It is used as a preservative to prevent microbial growth and spoilage in water-based paints, coatings, and adhesives.
- Personal Care Products: CMIT/MIT is utilized in shampoos, conditioners, lotions, and other personal care products as a preservative to inhibit the growth of bacteria, yeast, and mold.
- Industrial Processes: It is employed as a biocide in cooling towers, paper mills, cutting fluids, and metalworking fluids to control microbial contamination and maintain system efficiency.
- Water Treatment: Isothiazolinone is used in water treatment applications to prevent the growth of bacteria, algae, and fungi, ensuring safe and clean water.
- Household Products: It can be found in household cleaning products like detergents, fabric softeners, and disinfectants to provide antimicrobial properties and prevent product degradation.
- Textiles: Isothiazolinone is used as a biocide in textile processes to inhibit microbial growth, preventing odor and deterioration.
- Marine Antifouling: It is utilized in marine coatings to protect boats and ships from biofouling caused by marine organisms.
FAQ
No, CMIT/MIT is non-corrosive to common system metallurgy (carbon steel, copper, stainless steel) at recommended dosages, unlike oxidizing biocides.
CMIT is a chlorinated heterocyclic organic compound (CAS No. 26172-55-4). Because pure CMIT is chemically sensitive, it is professionally formulated in a stabilized aqueous solution—often with magnesium salts—to prevent degradation during storage and transit.
Yes, it is compatible with most corrosion inhibitors, scale controllers, and dispersants. For optimal results, avoid strong reducing agents and maintain system pH >6 during feed.
CMIT/MIT offers longer residual activity than DBNPA and broader spectrum than bronopol. It is often used in rotation with other biocides to prevent resistance development.
Packaged in 200-liter plastic drums, IBC containers (1000 liters), or according to customer requirements. Store in a cool, dry place. Shelf life is ten months.
Store Isothiazolinone (CMIT/MIT) in its original sealed container in a cool, dry, and well-ventilated area, protected from extreme temperatures and moisture.
